High-level meetings between Papua New Guinean and Australian officials are being held in Port Moresby this week as preparation for PNG hosting the APEC summit in 2018.
The PNG government said the meetings with Australia will identify areas where the two countries can work together to deliver safety and security preparations for the APEC summit.
The 2018 summit is expected to bring more than 10,000 delegates to PNG.
A statement from the PNG government said this week's meetings would also discuss "advance policy development".
This reportedly includes increasing regional trade and investment, and development in sectors including agriculture, maritime resources, tourism, mining and transportation.
